• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"secret ballot\") OR (((((\"secreto ballon\") OR (\"secretoso ballon\"))) OR (\"secreto ballone\"))))~".
• Removing quotes may allow a broader search: (( secret ballot ) OR ((((( secreto ballon ) OR ( secretoso ballon ))) OR ( secreto ballone ))))~.
• Adding a wildcard symbol may retrieve word variants: (("secret ballot") OR ((((("secreto ballon") OR ("secretoso ballon"))) OR ("secreto ballone"))))*.
